B7 bomber jacket: the ultimate USAAF shearling parka

While the B3 and B6 are among the most well-known aviator jackets of World War II, the B7 aviator jacket stands out for its unique design. A true shearling parka, the B7 was designed to offer maximum protection against the extreme cold faced by pilots and crews of the US Army Air Forces (USAAF).

The origin of the B7 jacket

The B7 was introduced in 1941 , at a time when heavy bomber missions like the B-17 Flying Fortress were carried out at very high altitudes, in unpressurized cockpits.
The temperature there could drop as low as -30°C, or even -40°C.

Faced with these extreme conditions, the B7 was designed as a long and ultra-insulating parka , capable of protecting aviators against the worst weather conditions.

The features of the B7

The B7 aviator jacket is instantly recognizable:

• Shearling leather , offering exceptional warmth and insulation.

• Long cut (parka type) extending below the waist, to better cover the body.

• A large sheepskin collar , sometimes accompanied by a detachable hood.

• A zipped front closure , protected by a buttoned tab.

• Two large, practical front pockets to keep your hands warm.

• Adjustable belt , allowing you to tighten the waist and limit heat loss.

The B7 was not just a jacket: it was a true thermal suit , designed for flights in extreme conditions.

The B7 during World War II

Worn primarily by bomber crews , the B7 offered unparalleled warmth, but its large size sometimes made it impractical for rapid movements.
This is why it was produced in limited quantities and gradually replaced by lighter models better suited to the needs of aviation.

Nevertheless, the B7 remains associated with the image of high-altitude aviators , braving the freezing cold over Europe and the Pacific.

The B7 jacket today

The original B7s are extremely rare, as they were manufactured in small series between 1941 and 1942.
Today they are among the most sought-after collectible military jackets , particularly appreciated for their authenticity and unparalleled comfort.

Specialist brands offer faithful reissues of the B7 , allowing enthusiasts to relive the experience of WWII aviators, with a unique and timeless style.

Conclusion: the B7, the most extreme of aviator jackets

The B7 aviator jacket is arguably the warmest shearling jacket ever produced for the USAAF.
A genuine sheepskin leather parka, it symbolizes the ingenuity and robustness of military equipment from the Second World War.

Today, the B7 remains a rare and mythical piece , appealing to both military history collectors and vintage aviator jacket enthusiasts.
